Gps Access Server In The Ace Framework Design And Implementation,

As China's logistics management information system development and the continuous increase of vehicles, vehicle operation management systems have become an increasing concern about the logistics of the owners. Today's computer technology, network technology, Global Positioning System (GPS) technology, information management technology matures, the scheduling system for the vehicle information management laid the foundation. Integration of a variety of technology GPS access server (GAS: GPS Access Server) is "GPS Logistics Information Management System," the core, the performance of the system determine the level of the pros and operating costs. Therefore, more and more developers started to pay attention to access to the server performance studies.Papers scheduling management system for vehicles in the GPS access server (GAS) related technology to achieve an in-depth exploration and study, analysis of its space and design problems related to the main challenges and proposed feasible solutions and reduce the difficulty of access server development And workload.1. ACE and the use of systematic framework for the development of rehabilitation to reduce the difficulty;2. Discussed the access server load balancing in the application and realization of the synchronization and the resulting problems and solutions;3. Handle a large number of client communication used by the I / O strategy, and on this basis, with the structure of the discussion;4. The idea of using modular design server, the server makes the expansion of the greatly enhanced;5. On the stability and high-performance servers to achieve was discussed.According to the analysis of the results of applications, given the overall structure from the server to server systems, transmission, servers, data access servers, alarm server, client access server component, and elaborated on the various server functions and the achievement of the programme.
